hello to everyone, i'm in the process of repairing this TV (L40FHD41YX9) which needs a back light inverter. I've found several replacement parts and one in particular im wanting to buy but the part came from a different TV. the part numbers and board numbers match but im needing to know if the this board will work in my RCA TV. the 1st image is the RCA part which needs replacing. the 2nd image is the TOSHIBA part which came from this model TV (40RV525R) which is a 40"LCD TV. thanks to everyone, mike
If you find one HV winding that is not responding, that may be due to shorted turns section and that will cause excess current pull and a triggering of the overload detection circuitry of the board and a quick turn off / shut down of this board. inverterreview.com
